Have you ever met a teacher who teaches in such a unique and refreshing way that you say, "I wish I could have had you as my teacher!?" Ms. Math hears this on a regular basis. Why? Because of her unique, fun, common sense approach to teaching math. Using art, hands on learning, and multiple ways to extend the learning, Ms. Math will captivate your child's inquiring mind and facilitate a true sense of numbers and mathematical concepts.  Enjoy a weekly video lesson and office hours twice monthly. Units include paper plate origami, puzzles, tessellations, dice games, line drawing and much more! Every month will cover a new unit, with lessons that build in complexity over the month. Great for both kids who love math and for those who struggle with math anxiety or keeping up.
